Continuation of application Serial No. 373,27'6, filed may 13, 1907. Renewed April 12, 1910, Serial No. 554,963. This application filed April 13, 1910. Serial No. 555,295.

To all whom it may concern Be it known that I, THOMAS G. PLANT, a citizen of the United States, residing at Boston, in the county of Sufiolk and State of l/lassachusetts, have invented an Improvement in lVork-Supports, of which the following description, in connection with the accompanying drawings, is a specification like letters on the drawings representing like parts.

The invention herein described relates to shoe supports, and more particularly to supports for sustaining a shoe in position while the heel is being treated, although, as will be understood by those skilled in the art, it may be employed for other purposes.

The aims and purposes of the present in vention are to provide a shoe support of the general type mentioned, which shall be simple in construction and eflicient l'or properly sustaining the shoe in position for treatment, all of which and other objects will best be made clear from the following description and accompanying drawings of one form or embodiment of means for carrying the invention into practical eirect, it being understood that the invention is not circumscribed by the illustrated details, but is defined in its true scope by the claims.

Theshoe support herein is of the laterally expansible type to be employed in connection with shoes which are treated while not mounted on the usual wooden last, and means are herein provided for causing such lateral expansion of the shoe support or jack as the shoe is moved to operative position with respect to the means for treating it, all as clearly pointed out in my prior application, Ser. No. 378,276, filed May 13, 1907, now Patent No. 958,306, to which reference may be had for a detailed description of means, such heel breasting means, for acting on the heel of a shoe sustained by the shoe support, which forms the subject of the present application.

In the drawings :-Figure l is a side ele vation showing sufficient of a heel breasting machine to make clear the relation of the present invention thereto and its construction; Fig. 2 is an enlarged detail detached view looking from the left at the lower part of Fig. 1; Fig. 3 is a sectional view on the line 33 of Fig. 2; Fig. 4 is an enlarged side View of the upper part of the shoe sup port, some oil? the parts being broken away;

Fig. 5 is a view of the parts shown in Fig. l, looking from the right; Fig. 6 is a sec-- tional View taken on the line (3-6 of Fig. 4: and Fig. 7 is a top or plan view of the jack plate to be described.

The machine frame for supporting the op eratlng parts oi. the machine may be of any usual or desired character, and herein is represented as a column 1 which may be of any form and kind suitable to the purpose intended. The lower portion of the column 1 is preferably provided with a lug or bracket 2 to which is fixed a pin 3, as by means of a set screw l, and pivotally mounted. on said pin 3 is the jack standard 5 which extends upward from its pivotal mounting through a guide plate 6 which is movable longitudinally oi the bracket or table 7. The jack standard is provided with a stop 8 adapted to engage a yielding hunter 9 as the jack standard is moved to the left, Fig. 1, to carry the shoe into operative position, as will hereinafter more fully appear At its upper portion, the jack standard 5 is provided with a socket or recess 10, Figs. 4:, 5 and (3, which may, if desired, be formed in the enlarged portion 11 at the upper part of the standard. This enlarged portion 11 is provided with guiding surfaces 12 adapted to slide between the guide portions 13 of the bracket or table 7, as clearly indicated in Fig. 6.

l lxtending into the socket 10 at the upper end of the jack standard is the jack post 14: which may, if desired, be provided with ashoulder 15 to rest upon the top extremity of the jack standard. The jack post 14 is conveniently retained in (.iperative relation with the jack standard by means of a set screw 16, l igs. 4 and 5, the end of which, it, enters a suitable recess in the jack post. As a further means oi. insuring the proper cooperative relation between the jack standard and jack post, a binding screw 18 extends through the upper portion of the jack standard 5 and engages a suitable recess in the jack post, as clearly indicated in Figs. 1', 5 and 6, and while such set screws furnish a convenient means for securing the jack standard and j aek post in proper relation, obviously other means may be employed.

The jack post 1 1: at its upper portion is preferably expanded or enlarged, as at 19, and has the supporting brackets 20 for a pin 21 on which the laterally expansible jack members 22 and 23 may be supported for lateral swinging movement, as will presently appear. Each of the laterally expansiblc jack members 22 and 23 is provided with a depending tail piece or toe 2e and 25, respectively, said toes being connected by a spring 26, Fig. 5, whereby said toes 24- and are normally drawn toward each other with a corresponding tendency to bring together or close the upper portions 22 and 23 of said laterally expansible jack members, somewhat in the manner of a pair of scissors, the construction being such that when the laterally expansible jack-members and their respective toes are not under the influence of any other disturbing force, the spring 26 will act to hold said jack members and toes in the relative positions indicated by Figs. and 6, with the upper ends of the jack members in closed relation;

Extending longitudinally through the jack post is is a jack expander 27, the lower end of which carries a collar 28, between which and the lower end of the jack post is interposed a spring 29, Figs. 4, 5 and-6, the construction being such that the jack expander 27 is normally held in lowered position by the spring At its upper portion the ack expander carries a pin 30 on which is mounted a roll 31 adapted, on upward movement of the jack expander 27, to pass between the toes 2% and 25 of the eX- pansible jack members and to separate the upper portions of said jack members. As a means for causing this upward movement of the jack expander and effecting such movement as the shoe is moved into operative position, as will hereinafter more fully appear, the present invention provides an expander actuator 32, Figs. 1, 2 and 3, the lower end of which is connected at 33 to a iii-zed collar 23% secured to the fixed pin 3. This fixed relation of the collar and pin 8 may be secured in any suitable manner, but, as represented in 1 3, the collar is formed with the split lugs and 36 which are connected by the binding screw 37, the construction being such that upon manipulation of the binding screw 37 the collar 34 may beiixed to the pin 3, as will be clearly understood by those skilled in the art.

The expander actuator 32 extends upward and is provided at its upper end with a seat 38 for the lower end of a spring 39 which is interposed between said seat and the lower end 40 of the jack expander, the construction being such that upon movement of the jack standard from the position shown in l to aposition farther to the left in order to carry the shoe into operative position, a differential longitudinal movement Will result between the jack standard 5 and the expander actuator 32, with the result that the spring 39 will transmit an upward force to the'lower end of the jack expander to thereby raise the same against the tension of its depressing spring 2-9 and perforce cause the roller 31 at the upper end of the jack expander to separa e the toes 24. and 25 and the jack members and 23 connected thereto. The relation be tween the springs 29 and 89 is such that wien the spring 39 is compressed by the relative upward movement of'the expander actuator 32% the jack standard moves to the left, the tension of the spring 29 will be yieldingly overcome, and thus the laterally cxpansible jack members will be yieldingly separated. jack members is of importance in order to permit the jack head, as will presently be described, to properly accommodate itself to the interior form and dimensions of the shoe, said springs 29 and 39 acting yieldingly to this end, the difference between their yielding force in opposite directions being the yielding expansible force exerted upon the laterally expansible jack members.

Each of the laterally expansible jack members 22 and '23 carries a hinged jack head, the two portions of which form the completed jack head. In the present form of the invention-each member has hinged to it, as at 41, Figs. 1 and 4, the head member 42, the under surface of one of which rests upon a plunger tfinormally pressed upward by a spring in seated in one of the jack members,

as clearly shown in Figs. i, 5 and 6. The

upward action of the plunger or pin 43 is limited by the knuckle or knife joint -15, the surfaces of which come together in a well understood manner and limit the upward turning movement of the head members about their pivotal mountings. T he pivotal mountings d1 of the head members are preferably located so that, when the jack standard has moved the shoe into operative position with respect to the breasting means, the tools which act upon the shoe will exert their force downward in a plane passing either through such pivotal mountings or to the left thereof, Figs. 1 and 4. 7

Each of the head members 42 is provided in upper surface with a series of holes 46, any one of which is adapted to receive a pin 4:7 projecting from the under surface of a jack plate as, Fig. 4, one of said jack plates being provided for each jack head member 42, and the upper surface thereof being preferably roughened to form a convenient character of sustainingmeans for-the interior of the shoe. By means of the series of holes L6, as hereinbefore described, the jack plates &8 may be adjusted longitudinally in either direction upon their respective jack head members to accommodate to the interior f0r- This yielding separation of the Cit mation and contour of the shoe. In order that said jack plates shall not swing laterally when the pins d7 are ad iusteiil in any one of the series of holes, the jack head memhere are each provided with a longitudinal. slot l9, F 4t, into which projects a pin 50, extending from the lower surface of each of the j acl; plates 4L8, the COTlSl/lfllCtlOn being such that upon proper adjustment of the jack plates they will conform to the interior contour of the shoe and afford a proper supporting surface therefor, as will be readily understood. Inasmuch as the jack head members, each of which is pivotally mounted to its laterally expa'nsible jack member, are separated more or less when the jack expander moves, as hereinbefore indicated, a guide pin 51 is secured to one of the head members 412, its other end projecting into a recess 52 in the companion head member, the construction being such that while the head members may separate by the lateral expansion of the jack members, in a manner hereinbefore described, the pin 5i will serve to guide said head members relative to each other and maintain them in proper lateral alinement.

The jack post 14: is preferably provided with a rearnuirdly extending bracket 53, on the top portion of which are a series of teeth 54.- which are adapted to be engaged by a locking device 55 supported in a bracket 56 projecting from the machine frame, the construction being such that when the jack standard and jack have been moved into operative position to place the shoe in operative relation with the machine tools, the lock 55 will engage with the teeth 5t and maintain the parts in their proper position during the operation of the tools.

It has not been deemed herein necessary to show and describe the heel breasting means and their manner of acting upon the heel of the shoe, since this means is clearly set forth in the prior patent heretofore mentioned.

Obviously changes may be made in the details of construction and the parts illustrated whereby the present invention may be carried into practical effect, and it is to be understood that the invention is not circumscribed by such details except as hereinafter pointed out by the claims.

While the term jack has been herein employed in describing the various parts, such the laterally expansible jack memhere, the head, jack plates, and so on, it is to be understood that such term is not one of limitation but is used merely as identifying the parts described and as broadly inclusive of any sustaining means or the parts thereof for sustaining a shoe for the action of the operating tools.
